I have something equivalent to this in my code:

mylist = ['x','y'
          'z']

(the real code has much longer contents, hence the line break ;-)

I think this should throw a parse error 'cos there's a missing comma.

What actually happens is it ends up as:

mylist = ['x','yz']

which is _really_ non-intuitive. I spent a good few hours trying to find the
source
of an exception in the Squishdot product for Zope until I noticed this.

I note that:
mystring = 'x''y'
is also legal, which I suspect is the roundabout source of this problem.

Sure that should raise an error and only the following should give the result
that that does:
mystring = 'x'+'y'

cheers,

Chris
